The multigroup transport theory is the basis for many neutronics modules. A significant point of the cross-section (XS) generation procedure is the choice of the energy groups' boundaries in the XS libraries, which must be carefully selected as an unsuitable energy meshing can easily lead to inaccurate results. This decision can require considerable effort and is particularly difficult for the common user, especially if not well-versed in reactor physics. This work investigates a genetic algorithm-based tool which selects an appropriate XS energy structure (ES) specific for the considered problem, to be used for the condensation of a fine multigroup library. The procedure is accelerated by results storage and fitness calculation speedup and can be easily parallelized. The extension is applied to the coupled code SIMMER and tested on the European Sustainable Nuclear Industrial Initiative (ESNII+) Advanced Sodium Technological Reactor for Industrial Demonstration (ASTRID)-like reactor system with different fitness functions. The results show that, when the libraries are condensed based on the ESs suggested by the algorithm, the code actually returns the correct multiplication factor, in both reference and voided conditions. The computational effort reduction obtained by using the condensed library rather than the fine one is assessed and is much higher than the time required for the ES search.

A lot of SSRs (simple sequence repeats) in peach and pear from enriched genomic libraries and in peach from a cDNA library were developed. These SSRs were applied to other related species, giving phenograms of 52 Prunes and 60 pear accessions. Apple SSRs could also be successfully used in Pyrus spp. Thirteen morphological traits were characterized on the basis of the linkage map obtained from an $F_2$ population of peach. This map was compiled with those morphological markers and 83 DNA markers, including SSR markers used as anchor loci, to compare different peach maps. Molecular markers tightly linked to new root-knot nematode resistance genes were also found. A linkage map including disease related genes, pear scab resistance and black spot susceptibility, in the Japanese pear Kinchaku were constructed using 118 RAPD markers. Another linkage map, of the European pear Bartlett, was also constructed with 226 markers, including 49 SSRs from pear, apple, peach and cherry. Maps of other Japanese pear cultivars, i.e., Kousui and Housui, were also constructed. These maps were the first results of pear species.

The purpose of this study is to apply the international quality certification system to service quality evaluation in library and information service centers. The study compared various aspects of their quality certification systems and considered application studies of foreign libraries. The results of this study illustrate that TQM based quality certification systems-Doming Quality Prize, Malcolm Baldrige National Quality Awards. European Quality Awards-reflects a broader, more dynamic and custome-oriented quality concepts. On the contrary, ISO 9000 Standards are based on a narrow, static and in house-oriented quality concepts emphasizing conformance to specifications.

This study aims to analyze in depth the operation of the Public Lending Right(PLR) system that is implemented in 34 countries in the world in order to propose the ideal operation of PLR system. The PLR system is that authors receive payment because they lose the sales opportunities due to the loan of their books by libraries. Among 34 countries implementing the PLR system, 31 are European countries and 20 countries enforce the copyright law for the operation of the PLR system. Fund for the PLR is financed by the budget of the central government in 25 countries and payments are made on the basis of loans data in 20 countries. Writers, illustrators, translators are eligible to receive payments in many countries. 17 countries provide payments to the authors who have contributed to books lent out by libraries.

The purpose of this study is to make a contribution to the effective management of medical literature in Korean libraries and specifically to help to select medical books and periodicals by determining the value and life of medical literature by means of citation counting and analysis. This report will present methods of calculation and data collection to measure the importance, half life of medical literature and the authority of author for Korean medical libraries. The writer conducted comparative studies based on data covering a two-year period, 1970-1971, using about 16,899 citations in 1,032 articles of the above journals. The references and citations are counted and analyzed by the number of authors, periodicals. books and publication dates. By the following ratio. calculated by the citation counting and analysis, we can decide the rates of medical periodicals to books, foreign literature to domestic literature and literature of the most numerously cited. authors, for the selecting method of Korean Medical libraries. (1) It is disclosed that 61 main authors are cited 9 times. Most of them are Western authors, they are cited 14,374 times which represents 88.6 % of the total citations. (2) The cited medical literature is classified as follows: The ratio of cited medical periodicals to the cited medical books is 82.0%. (The books at a rate of 18.0%.) Therefore, the wnter concentrated the efforts on the analysis of periodicals. (3) Classification of the periodicals by countries indicates that about 11.2% of total citations are made from Korean medical literature. The medical activities in Korea are dependent on the advanced foreign countries at ratio of 88.8%. Of the foreign medical periodicals cited, Japanese literature represents only 4.5% while literature of European countries and America constitutes 84.3%. (4) If medical journals are arranged in order of decreasing productivity of articles on a given subject, they may be revealed that it is necessary to have 98 titles of key journals to cover 60% of information in the field of medical science and 60 titles for an average of 50%. (5) For the purpose of measuring the life of medical literature in Korea, the writer has calculated the half lives of periodicals and books as follows: Kinds of Literature 1. Periodicals 2. Books 3. Whole literature Half-lives 7.75 years 4.11 years 6.37 years (6) The half lives of domestic and Japanese literature in the medical science are comparatively short.

The article is based on a model, in the context of which there are two fundamental building blocks of basic library skills and skills in the use of information technology. The former are formed within the framework of educational programs for users of academic libraries, the latter are formed within the framework of initiatives such as the European Computer Driving License. Between the basic and the highest levels of the concept of "information literacy" there are seven heading skills and attributes, the repeated practice of which leads from the position of a competent user to an expert level of reflection and critical awareness of information as an intellectual resource. Freshmen will likely be at the beginning of the arrow, probably practicing only the first four skills, while graduate students and young scientists will be closer to the end and will use seven skills.

Post-neutron emission fission product mass distributions are calculated by using pre-neutron emission fission product yields (FPYs) and neutron multiplicity. A semi-empirical model is used to calculate the pre-neutron FPY, first. Then the neutron multiplicity for each fission fragment mass is used to convert the pre-neutron FPY to the post-neutron FPY. In doing so, assumptions are made for the probability for a pre-emission fission fragment with a mass number A^* to decay to a post-emission fragment with a mass number A. The resulting post-neutron FPYs are compared with the data available. The systems where the experimental data of not only the pre- and post-neutron FPY but also neutron multiplicity are available are the thermal neutron-induced fission of ²³³U, ²³⁵U and ²³⁹Pu. Thus, we applied the model calculations to these systems and compared the calculation results with those from the GEF and the data from the ENDF and the EXFOR libraries. Both the pre- and post-neutron fission product mass distributions calculated by using the semi-empirical model and the neutron multiplicity reproduce the overall features of the experimental data.

Plan S is a policy that mandates research papers supported by specific funders such as the European Community be published in open access journals. The funder supports APC to researchers, providing a chance to advance the era of gold open access, and is expected to bring significant changes to the scholarly publishing ecosystem. This study explored the impact of Plan S from the perspective of each stakeholder of the scholarly publishing ecosystem, such as funders, academic societies or publishers, authors, and libraries, through a review of previous studies. In addition, the status of Korean gold open access publishing and position for each stakeholder were identified through the collected data analysis. As a result of the analysis, the share of publishing gold open access journals in Korea was 22%, which was less than 26% worldwide. Korean funding agencies were predicting and preparing for the impact of Plan S. On the other hand, Korean academic societies produce about 70% of all papers, but there are not many open access papers except medicine (51%). The response of the Korean library was not sufficient, and it contrasted with the activities of librarians in the U.S. that actively provide research support services based on the research lifecycle. It was suggested that Korean libraries should also actively try to change the role of librarians; advising researchers to plan open access publishing in grant project applications, consulting on copyrights, and so on. This study identified the background, principles, and impact of Plan S policy that would be effective in 2021 and examined the response situation in Korea. This study is valuable in that it served as the necessary basis for revitalizing the academic publishing ecosystem in Korea.
